Discharge valve mechanism in compressor

摘要

A discharge valve mechanism in a compressor for compressing refrigerant gas includes a valve plate and a discharge valve plate. The valve plate forms a discharge port into which the compressed refrigerant gas is discharged. The discharge valve plate is located between the valve plate and a rear housing and includes a support portion, a connecting portion and a discharge valve. The support portion is sandwiched between the valve plate and the end surface of the rear housing. The connecting portion is bendably cantilevered from the support portion. The connecting portion extends to an opposite side of the discharge port so as to bypass the discharge port from the support portion. The connecting portion has a free end portion. The discharge valve extends from the free end portion to the discharge port toward the support portion for opening and closing the discharge port.
